Diagram

Note: When you solder the VTX, pls follow the diagram for A02 VTX, in which the second port under ANT(MMCX) is GND, and it corresponds to the black wire of the 6-Pin FC Cable. If you have received the VTX with a diagram of "SW" or just black in the GND place, Please don't worry, it's just the typographical error, we have corrected it in the next batch.

How to Connect with FC

Here is the diagram about how to connect the VTX to Toothpick F722 2-6S AIO Brushless Flight Controller 35A(BLHei_32). The color of the lines in the diagram is the same as the 6-pin connector's wires' color.

How to Use the PitMode & Change the Frequency and Power

PitMode allows racers to power up their video transmitters during race events without interfering with other racers, and it still has the ability to change VTX settings or do some testing. The range is limited to 2-3m and transmission happens on the selected frequency.

The PitMode is active when the Red/Green/Blue Power LED flash.

How to active and exit the PitMode

Press the Button on the VTX twice to active Pitmode, double-press again to return to the previous power state.

How to Change Frequency & Channel & Power

Enter the OSD menu by radio transmitter sticks ( Pitch Stick UP and Yaw Stick Left). Then FEATURES -> VTX SA to change the frequency and power.
